   phone screen -- the same `min(500px, 80vh)` is set on the header
   widget's own config.height (theme.json) as a min-height fallback for
   when JavaScript/CSS min() support is unavailable.

   The banner photo (static/img/banner.jpg -- a wide panorama with a
   woman and dog silhouetted at its right edge, over a dark, noisy band
   along its bottom ~40%) is anchored `right bottom` and scaled with
   `cover`: whichever axis the box is proportionally wider/taller than
   the photo on, only the photo's *top* and *left* are ever cropped away
   -- its right edge (the woman and dog) and the whole of its bottom
   dark band always stay in frame, at every screen width. */

   no wrapper div of this theme's own: styling therefore targets
   .area-header h1 / .area-header .tb-tagline directly rather than a
   bespoke class, so it applies to *any* blog's own stored banner
   content, including one customized (or carried forward from an older
   version of this theme, before this file existed) with the plain
   `<h1>...</h1><p class="tb-tagline">...</p>` markup -- there is no
   wrapper class such a blog's own stored config could be missing.

   .tb-header-inner itself is absolutely positioned and pinned to the
   bottom 40% of the banner -- the same fraction the photo's own dark
   band always occupies at the bottom of the box, whatever the crop --
   flush to that band's bottom-left corner, so the text is always
   readable against that solid dark background rather than over the
   sky, and a wrapped two-line title can never inflate it past the
   banner's own fixed height (see .area-header above) -- it just gets
   less room and its clamp()'d font shrinks instead. */
